From 3.0.0 until 3.3.53, a disabled RichEditor field rendered its raw state without sanitizing HTML. Where the data stored in this field's state isn't sanitized already when the form state was filled, an attacker could plant malicious HTML or JavaScript and achieve XSS that executes for users who view the form. This vulnerability is fixed in 3.3.53."

Desde la versión 3.0.0 hasta la 3.3.53, un campo RichEditor deshabilitado renderizaba su estado sin procesar sin sanear HTML. Donde los datos almacenados en el estado de este campo no están ya saneados cuando se rellenó el estado del formulario, un atacante podría insertar HTML o JavaScript malicioso y lograr XSS que se ejecuta para los usuarios que ven el formulario. Esta vulnerabilidad se corrigió en la versión 3.3.53."
